and use the same, reference being had to the accompanying drawings,forming part, of this specification, in which Figure 1 is a longitudinalvertical sectional view of my improved machine Fig. 2 is a fragmentaryplan view; Fig. 3 is a modified form; 'Fig. 4 shows a modified form. y

This invention relates to a new and useful improvement in single strandwire glass machines. By single strand I mean that instead of embedding awire mesh into the Y sheet of glass, as has heretofore been largelypractised, I propose to embed oneor more single strands of Wire into thesheet of glass, I said strands being so arranged with respect to eachother that they are electrically insulated from each other, the ends ofthe Wires preferablyprojecting beyond the sheet of glass to afford meansforelectrically connecting said wires together, as illustrated in anaccompanying application filed by me of even date and serially numbered468,508.

. The single strand sheets of glass made by my improved machine andaccording to my method are useful for various purposes,

' among which may be-mentioned dust "and wind guards for-automobiles,vault and jail lights, show cases, etc., where the electric,

burglar alarm element is valuable, and

other places where it'is desiredto have single strands of wire insteadof wire as has heretofore been used.

My present invention consists in a mamesh chine for and method'ofmanufacturing single strand Wire glass, as will hereinafter be set forthand afterward pointed out in the claim.

Specification of Letters Patent. P t t d J 29, 1 915, Application filedDecember 21, 1908. Serial No. 468,508. A

priately mounted on the frame 1, or an extension thereof, which rollerinitially spreads the pour 7 of molten glass into sheet form asindicated at 7 I 8 is an extension of frame 1 for supportmg the singlestrands of Wire and their, friction devices.

9 are a series of bobbins or spools loosely arranged on a suitablecross-shaft and each containing a strand of wire of appropriate gage.

10 is a plate slotted for the passage of the several strands ofwire. 11is a bar having recesses or slots registering with the grooves or slotsin the plate 10 and forming a guiding opening through which the strandsof wire pass.

12 are eccentrics Working in the slots or grooves in the plate 10, andWhose function is'to keep the single strands of wire more machine.

13 is a roller under which the wires pass in entering the grooves inplate 10.

1% is a flat bar arranged at the lowe'rend of plate 10, said bar servingto'confine the wires in grooves in said plate 10.

15 is the embedding roller-which, in this case, is smooth, and underwhich the single strands of wire pass, said wires being embedded in thetop sur ace of the sheet 7 I 16.is a finishing ljller mounted in thesaid frame 1, or an extension thereof, for spreading the second pour 7of glass in sheet form over the single strands of wire and making thecomplete sheet of glass 7 In operation the pour 7 is dumped'onto thefront end of table 3 and said table advances until the ends of the wireX are in 17 over a spacing bar 18 on the forward end oftable 3. Afterthe ends of the single strands of wire are secured in position at theforward end of the table. the table is further advanced and the secondpour 7 made, after which the table is moved for-- ward until the poursof glass are spread. The Wires are then severed and the complete sheetof glass annealed in the usual way In Fig. 3 l'. have shown a modifiedform of my invention, in Which,-instead of embedding single strands ofwire onto the surface of the first formed sheet of glass 7 by means of asmooth embeddin roller, I use a longitudinally fluted embedding roller15 deeply into the surface of the sheet 7 v, leav ing transverselydisposed ribs or corrugations on said sheet as shown. These may besmoothed by a finishing roller 16, or a second pourcan be employed as,heretofore described. V v v It Will be obvious that the initial roller 6can be dispensed with and the first pour 7 spread out by the rollers 15or 15, in which event-the strands of Wirecould be fed from in front andaround the rollers 15 and 15. i

The feature of placing an independently operable and individual tension,on the several strands, I deem quite important because the wire feed tothe molten glassv is usually of normal temperature and naturally becomesheated and expands.

uniform in all the strands of wire. Where a number of 'strands'ai'ebeing fed to the.

lhis eXpansion'is not glass, there might be as many difi'erent degreesof expansion as there are difi'erent wires, and unless some indivldualmeans Were provided to take up the slack caused by these variousexpansions some of the strands would be comparatively taut, while theothers would be slack, Which-slackness In a device for manufacturingWire glass,

the combination of forming rolls, Wire reels for supporting separatestrands of fivire, a table, a slotted guide plate for guiding theseparate strands of wire fromsaid reelsto saidtable, and adjustablefriction elements cooperating with said slotted plate to grip the wiresindividually toapply selectively variable tension to the difierentWires.

In testimony whereof I hereunto affix my" signature in the presence oftwo WItHGSSGS',
